Sending a question to the users
How can I send a question in an email to the persons who posted the adds in a specific category adds?
For example: There is a software category in which are 20 adds. I'm looking for some general questions about the Cad software and I would like to be send my question to all posters who have adds about this software.
The questions would be send by users and not by the admins.
Thanks in advance for your help and suggestions.
